Hi mosh513,
I’m glad you’re making progress, and congratulations on your foundation and topper purchase! :cheer:
My best recommendation for latex layers would be the members of the site listed in the beginning of post #21 here in latex section, two of whom you’re already considering and the third (SleepEZ) you’ve already purchase a topper from. I don’t have any reliable recommendations for latex componentry in your area.
Keep us updated!
